Messages in secret language

Sometimes you want to get a notification on your PC that you want to keep secret from others.

I always send those kinds of secret messages to me via Morse code (as sound). I know morse but people around me don't.
So that's how I can hear special messages in intelligible Morse code.

It works particularly well when I share my screen during a Teams meeting. I hear the notification but the other participants do not.

The tool is: cw (installable with sudo install cw).

Example of usage in a script:
echo "hello" | cw -w 18 -e
The number after -w is the speed in words per minute.

Scripts are super useful because they take little time to create - they are often short - and they make life a lot easier.
